What else can it be, if it happens all the time with this driver? Of the times I have used the service, it was only once on time leaving Sunderland - and that's when it was a different driver. This driver pulled in at 05:00am on the dot and waited on the layover for a few minutes before letting passengers on.

If it was happening every once in a while or happened with multiple drivers, I'd suggest first check defects in the depot and that was the reason why the bus didn't depart Park Lane on time - but this isn't the case.
